摘　　要：《信号与系统》是电类专业的一门重要的专业基础课程。该门课程对数学、电路等知识的较高要求,使许多概念非常抽象,难以理解,不断探索新型的教学方法对该门课程尤其重要。MATLAB软件提供了强大的图形绘制功能,将其融入《信号与系统》课程的教学,加深了学生对生硬知识难点的理解,提高了学生的学习兴趣和实践动手能力。文中介绍了MATLAB软件的特点,详细给出了MATLAB软件在《信号与系统》课程教学中的几个应用实例,并分析了借助MATLAB软件,如何理解《信号与系统》中的抽象概念。Signals and Systems is an important basic specialty course in Electrical and Electronic specialty. The course requires higher mathematics and circuit analysis knowledge,thus many conceptions are very abstract and difficult to comprehend. Seeking after newstyle teaching methods ceaselessly is more important to this course. MATLAB Software provides powerful graphics plotting function. Integrating MATLAB Software into Signals and Systems Course Teaching can make the students to understand difficulties and enhance the study interest and practice ability. The characteristics of MATLAB Software were discussed. Several application examples of MATLAB Software in Signals and Systems Course were given in detail. How to understand the abstract conceptions of Signals and Systems in virtue of MATLAB Software were analyzed.
